In monkeys trained to detect and discriminate noxious heat stimuli, morphine microinjected into the medullary dorsal horn attenuated the perceived intensity of noxious heat in a dose- and stimulus-dependent fashion. These data demonstrate a pharmacologically specific effect of opiates on the sensory intensity component of pain at the earliest central relay pathway transmitting noxious information. © 1986.
